Police investigating the break-in at The High Street Delicatessen in Newtown last month have issued a photograph of bottles of rum they want to track down.
The Welsh seaweed spiced rum, called Barti Ddu Rum, isn't available anywhere in town other than at the delicatessen where it was stolen from along with a charity cash box sometime on the 26 August.
"You cannot buy this bottle anywhere else in Newtown. They are rather unique," said PC Tanya Jarman.
Anyone offered a bottle of the rum or who might have seen it, should contact Newtown Police by telephoning 101.
